Characteristics of nanosecond pulsed plasma aerodynamic actuation in compressor cascade internal flow environment

In order to obtain the characteristics of nanosecond pulsed plasma aerodynamic actuation (NSPAA) in compressor cascade internal flow environment, we established a phenomenological model to simulate the pressure and temperature of NSPAA. The calculated results are in accordance with experimental results, which verify the reliability of the model. Then we imposed the NSPAA in different flow fields of the compressor cascade passage in static air and with high-subsonic incoming flow. The calculation results show that the NSPAA has a limited ability to accelerate airflow, which acts mainly as the shock effect on the flow field. The NSPAA induces strong compressive wave in static air, high-speed main stream flow field, and separation zone, which has a stronger shock effect on the flow filed in high-speed main stream flow field and separation zone. The NSPAA arouses temperature in discharge region, but the temperature decreases quickly after the actuation. Meanwhile, the temperature in separation zone and main stream decreases faster than that in static air.
